International Clinical Trials


What is a clinical trial?

A clinical trial is scientific research. It investigates whether a new drug can be approved or proven drug therapy concepts can be optimized in clinical routine. Clinical trials are used to test the efficacy and safety of new procedures or drugs. The methodological structure of a study depends on the question to be investigated.

In Germany testing of a new drug takes place in four successive stages (study phases). The Bundesinstitut für Arzneimittel und Medizinprodukte (BfArM) or Federal Institute for Drugs and Medicines provides an overview of this.
Participation in a clinical trial opens up opportunities, but also entails risks. Study participants must be informed about both in advance.
Patients participating in a study must fulfill prerequisites that are defined for each study (both inclusion and exclusion criteria).

What can clinical trials do for me?

Clinical trials are essential to achieve progress in cancer treatment. They are also essential to develop the best and most effective treatment strategies for patients. Participation in clinical trials can be beneficial (quality attribute & prognostic factor). In your individual case, talk to your physician about current studies.

  • certain concomitant diseases may also exclude
  • depends on the individual case
